With last week being father's day, my son picked up on this and announced "it's Tommy's day today" until I told him every day was Tommy's day in this bloody house.It's a Sunday. Sunday is my day.
That means she takes the kids to visit grandparents & stuff from 1/2pm ish whilst I wank/watch tv/drink/watch sports/sleep/read books (delete as applicable).
She'll be back at about half 8 so the kids can go a kip. Sundays are boss.
